eco-friendly Button
You may turn off the port LEDs to conserve electricity when you are not
monitoring the switch. The LEDs are toggled with the eco-friendly button
on the front panel of the switch or the ECOFRIENDLY LED and NO
ECOFRIENDLY LED commands in the Global Configuration mode of the
command line interface. The switch is said to be operating in a low power
mode when the LEDs are turned off.
Operating the switch in the low power mode with the LEDs turned off does
not interfere with the network operations of the device.
The Switch ID LED is always on, but it displays different information
depending on whether the LEDs are on or off. When the LEDs are on, the
ID LED displays the switches ID number. When the switch is operating in
the low power mode with the LEDs off, the LED indicates whether the
switch is a stand-alone unit or the master or member switch of a VCStack,
as detailed in Figure 8 on page 35.
Note
Before checking or troubleshooting the network connections to the
ports on the switch, you should always check to be sure that the
LEDs are on by either pressing the eco-friendly button or issuing the
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the command line interface.
